Diving in Comoros
Including Grand Comore Reefs and Mohéli Marine Park. On the map.
The vibe
Diving in these waters is a raw, expedition-style endeavor that feels far removed from the polished infrastructure of typical tropical dive hubs. The visibility is consistently excellent throughout the year, though the seas are most manageable during the calmer dry season. It is a quiet, DIY-heavy scene where you will need to coordinate directly with local boat owners to reach the outer drop-offs.
You will need to present your certification card to local operators.

Grand Comore Reefs

The volcanic coastline of Grand Comore provides steep drop-offs and lava-formed reef structures that attract a wide variety of pelagic species. Divers often encounter large schools of jacks and reef sharks along the rugged, deep-water walls surrounding the island.
Access. Dive centers are concentrated in and around the capital, Moroni, providing boat access to the island's most prominent wall and reef sites.
Notes. Strong currents can occur; advanced buoyancy control is recommended for wall sites.

Mohéli Marine Park

As the Comoros' only national park, Mohéli offers pristine coral reefs and dramatic underwater topography teeming with marine life, including sea turtles and humpback whales. Divers can explore vibrant pinnacles and slopes that remain largely untouched by mass tourism.
Access. Access is primarily via dive operators based in Fomboni or through specialized liveaboards that visit the island's southern coast.
Notes. Best diving season is from May to October; marine park fees apply.
